DETAILED DESCRIPTION

Detailed embodiments are disclosed herein. However, it is understood that the disclosed embodiments are merely examples, which may be embodied in various forms. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a basis for the claims and as a representative basis for teaching one skilled in the art to variously employ the embodiments in virtually any appropriately detailed structure. Further, the terms and phrases used herein are not intended to be limiting, but to provide an understandable description of the present disclosure.

The terms “a” or “an,” as used herein, are defined as one or more than one. The term “another,” as used herein, is defined as at least a second or more. The terms “including” and/or “having”, as used herein, are defined as comprising (i.e., open transition). The term “coupled” or “moveably coupled,” as used herein, is defined as connected, although not necessarily directly and mechanically.

In general, the embodiments are directed to bodily implants. For example, in some embodiments, the bodily implant is configured to be disposed within a pelvic region of a patient. For example, the bodily implant may be a penile implant. In other embodiments, the implant is configured to be disposed within a different portion of the body of the patient. The term patient or user may hereafter be used for a person who benefits from the medical device or the methods disclosed in the present disclosure. For example, the patient can be a person whose body is implanted with the medical device.

FIG. 1 schematically illustrates a bodily implant 100. In the illustrated embodiment, the implant is an inflatable bodily implant. The bodily implant includes a fluid reservoir 102, an inflatable member 104, and a pump assembly 106. The fluid reservoir 102 is operatively coupled to the pump assembly 106 and the pump assembly 106 is operatively coupled to the inflatable member 104. The pump assembly 106 is configured to transfer fluid between the fluid reservoir 102 and the inflatable member 104 according to an aspect.

In some embodiments, the implant 100 is a penile implant. In some such embodiments, the inflatable member 104 may be implanted into the corpus cavernosae of the user, the fluid reservoir 102 may be implanted in the abdomen or pelvic cavity of the user (e.g., the fluid reservoir 102 may be implanted in the lower portion of the user's abdominal cavity or the upper portion of the user's pelvic cavity), and the pump assembly 106 may be implanted in the scrotum of the user.

The pump assembly 106 includes a pump bulb 108 and an actuator or a deflation mode actuator 112. In an inflation mode, the user may operate the pump bulb 108 (e.g., squeeze the pump bulb 108, release, then squeeze again, etc.) to transfer fluid from the fluid reservoir 102 to the pump assembly 106, and from the pump assembly 106 to the inflatable member 104 such that a desired rigidity is achieved in the inflatable member 104. In order to deflate the inflatable member 104, the user may locate the deflation mode actuator 112, and activate the deflation mode actuator 112 to place the implant 100 in a deflation mode.

In some embodiments, the deflation mode actuator 112 is movably coupled to a pump assembly or a valve body. In some examples, the deflation mode actuator 112 includes a protrusion, that when pressed, causes the valve body to define a fluid passageway from the inflatable member 104 to the fluid reservoir 102 in order to deflate the inflatable member 104. In some examples, the deflation mode actuator 112 includes a push rod or button. In some examples, the user presses the deflation mode actuator 112 once (e.g., does not need to hold the deflation mode actuator 112) to cause fluid to drain from the inflatable member 104.

The pump bulb 108 may be a flexible member defining a cavity. In some embodiments, the pump bulb 108 is coupled to and extends from the valve body. The pump bulb 108 may be a squeeze pump. The pump bulb 108 may use suction and pressure to move the fluid in and out of the cavity of the pump bulb 108 in the inflation mode. For example, the user may depress or squeeze the pump bulb 108 to expel the fluid out of the cavity, and, when the flexible member returns to its original shape, the resulting suction pushes the fluid into the cavity of the pump bulb 108. In some examples, the pump bulb 108 may have a bulb spring rate that is designed to refill the pump bulb 108 in a selected time frame.

In the illustrated embodiment, the pump bulb 108 includes a control feature 110. The control feature 110 is configured to allow the user to locate and grasp the pump bulb 108 during use of the device. For example, when the implant 100 is disposed within the body of the patient, the patient can locate the pump bulb 108 by feeling for the control feature 110. In some embodiments, the control feature 110 is shaped or otherwise configured to allow the user to understand the orientation of the implant within the body. Additionally, in some embodiments, the control feature 110 may facilitate the actuation of the pump bulb. For example, in some embodiments, the control feature 110 may allow or facilitate the user to actuate the pump bulb 108 by grasping the pump bulb 110 with a full hand or with a few fingers or either method.

In some embodiments, the control feature 110 is disposed on an outer surface of the pump bulb. For example, in some embodiments, the pump bulb 108 includes an inner surface that defines an internal channel or cavity. The outer surface is disposed opposite the inner surface. The control feature 110 may extend from, protrude, or otherwise be disposed on the outer surface of the pump bulb 108.

In some embodiments, the control feature 110 is a tactile feature. In some embodiments, the control feature 110 is a single projection or member. In other embodiments, the control feature 110 is a series of projections. In some embodiments, the control feature 110 is a series of projections that are arranged in a specific pattern.

In some embodiments, the pump bulb 108 is formed of an implantable grade silicone. In some embodiments, the control feature 110 is integrally or unitarily formed with the pump bulb 108. In other embodiments, the control feature 110 is formed separately from the pump bulb 108 and is coupled to the pump bulb 108. For example, in some embodiments, the control feature 110 may be coupled to the outer surface of the pump bulb 108 using an adhesive.

In some embodiments, the control feature 110 extends from the outer surface of the pump bulb 108 a sufficient distance such that bodily tissue does not surround the pump bulb to hide or mask the control feature 110. In other words, in some embodiments, the control feature 110 extends such that tissue encapsulation of the implant 100 or the pump bulb 108 does not prevent the user from feeling or detecting the control feature 110.

FIG. 2 illustrates an inflatable penile prosthesis or implant 200 having a pump assembly 206 according to an aspect. The penile prosthesis 200 may include a pair of inflatable cylinders 210, and the inflatable cylinders 210 are configured to be implanted in a penis of the patient. For example, one of the inflatable cylinders 210 may be disposed on one side of the penis, and the other inflatable cylinder 210 may be disposed on the other side of the penis. Each inflatable cylinder 210 may include a first end portion 224, a cavity or inflation chamber 222, and a second end portion 228 having a rear tip 232.

The pump assembly 206 may be implanted into the patient's scrotum. A pair of conduit connectors 205 may attach the pump assembly 206 to the inflatable cylinders 210 such that the pump assembly 206 is in fluid communication with the inflatable cylinders 210. Also, the pump assembly 206 may be in fluid communication with a fluid reservoir 202 via a conduit connector 203. The fluid reservoir 202 may be implanted into the user's abdomen. The inflation chamber or portion 222 of the inflatable cylinder 210 may be disposed within the penis. The first end portion 224 of the inflatable cylinder 210 may be at least partially disposed within the crown portion of the penis. The second end portion 228 may be implanted into the patient's pubic region with the rear tip 232 proximate the pubic bone.

In order to implant the inflatable cylinders 210, the surgeon may first prepare the patient. The surgeon often makes an incision in the penoscrotal region, e.g., where the base of the penis meets with the top of the scrotum. From the penoscrotal incision, the surgeon may dilate the patient's corpus cavernosae to prepare the patient to receive the inflatable cylinders 210. The corpus cavernosum is one of two parallel columns of erectile tissue forming the dorsal part of the body of the penis, e.g., two slender columns that extend substantially the length of the penis. The surgeon will also dilate two regions of the pubic area to prepare the patient to receive the second end portion 228. The surgeon may measure the length of the corpora cavernosae from the incision and the dilated region of the pubic area to determine an appropriate size of the inflatable cylinders 210 to implant.

After the patient is prepared, the penile prosthesis 200 is implanted into the patient. The tip of the first end portion 224 of each inflatable cylinder 210 may be attached to a suture. The other end of the suture may be attached to a needle member (e.g., Keith needle). The needle member is inserted into the incision and into the dilated corpus cavernosum. The needle member is then forced through the crown of the penis. The surgeon tugs on the suture to pull the inflatable cylinder 210 into the corpus cavernosum. This is done for each inflatable cylinder 210 of the pair. Once the inflation chamber 222 is in place, the surgeon may remove the suture from the tip. The surgeon then inserts the second end portion 228. The surgeon inserts the rear end of the inflatable cylinder 210 into the incision and forces the second end portion 228 toward the pubic bone until each inflatable cylinder 210 is in place.

A pump bulb 208 of the pump assembly 206 may be squeezed or depressed by the user in order to facilitate the transfer of fluid from the fluid reservoir 202 to the inflatable cylinders 210. For example, in the inflation mode, while the user is operating the pump bulb 208, the pump bulb 208 may receive the fluid from the fluid reservoir 202, and then output the fluid to the inflatable cylinders 210. When the user switches to the deflation mode, at least some of the fluid can automatically be transferred back to the fluid reservoir 202 (due to the difference in pressure from the inflatable cylinders 210 to the fluid reservoir 202). Then, the user may squeeze the inflatable cylinders 210 to facilitate the further transfer of fluid through the pump to the fluid reservoir 202.

In the illustrated embodiment, the pump assembly 206 includes an actuation member 212. The actuation member 212 may be used by the patient to toggle or switch the penile implant 200 from its inflate mode to its deflate mode.

FIGS. 3 and 4 illustrate the pump assembly 206. In the illustrated embodiment, the pump bulb 208 includes an outer surface 260. The pump bulb 208 also includes an inner surface 262. The inner surface 262 is disposed opposite the outer surface 260. The inner surface 262 defines the cavity 264 that is configured to house or receive the fluid as it is passed through the penile implant 200.

The pump assembly 206 includes a control feature or member 210. In the illustrated embodiment, the pump assembly 206 includes a plurality of projections that form the control feature or member 210. The pump assembly 206 includes a plurality of horizontal projections 272 and a plurality of vertical projections 274. The horizontal projections 272 and the vertical projections are coupled to and extend from the outer surface 260 of the pump bulb 208. In some embodiments, the horizontal projections 272 and the vertical projections 274 are integrally or unitarily formed with the pump bulb 208.

In the illustrated embodiment, the projections 272 and 274 each have a height H (the distance that the projections 272 and 274 extend from the outer surface 260 of the pump bulb 208), a length L, and a width W. The lengths of the projections 272 and 274 are larger or greater than the widths of the projections 272 and 274. In the illustrated embodiment, the length L of each of the projections defines an axis A of the projections. Specifically, the length L extends along the axis A.

The pump bulb 208 has a first end portion 280 and a second end portion 282 disposed opposite the first end portion 280. The pump bulb 208 defines an axis AX that extends from the first end portion 280 to the second end portion 282. In the illustrated embodiment, the projections 272 and 274 extend substantially linearly in the length direction (along the length L and in the direction of the axis A). The horizontal projections 272 extend (along the length L and in the direction of the axis A) substantially perpendicular to the axis AX of the pump bulb 208 and substantially perpendicular to the axis of the vertical projections 274. The vertical projections 274 extend (along the length) in a direction substantially parallel to the axis AX of the pump bulb 208.

In the illustrated embodiment, the pump assembly includes six horizontal projections 272 and twelve vertical projections 274. In other embodiments, the pump assembly includes a different number of horizontal projections (such as more than twelve or less than twelve). Similarly, in other embodiments, the pump assembly includes a different number of vertical projections (such as more than six or less than six).

In the illustrated embodiment, the horizontal projections 272 and the vertical projections 274 help prevent the pump bulb 208 from slipping from the grip of the user. For example, the horizontal projections 272 may help prevent the pump bulb 208 from slipping vertically and the vertical projections 274 may help prevent the pump bulb from slipping horizontally. The projections may also help prevent the pump bulb 208 from rotating during the pumping or actuation by the user. In some embodiments, the projections 272 and 274 help or facilitate the locating of the deflation mode actuator 212.

The pump bulb 308 has a first end portion 380 and a second end portion 382 disposed opposite the first end portion 380. The pump bulb 308 defines an axis CX that extends from the first end portion 380 to the second end portion 382. In the illustrated embodiment, the projections 372 and 374 extend substantially linearly in the length direction (along the length L and in the direction of the axis C). The horizontal projections 372 extend (along the length L and in the direction of the axis C) substantially perpendicular to the axis CX of the pump bulb 308 and substantially perpendicular to the axis of the vertical projections 374. The vertical projections 374 extend (along the length) in a direction substantially parallel to the axis CX of the pump bulb 308.

In the illustrated embodiment, the projections 472 and 474 each have a height H (the distance that the projections 472 and 474 extend from the outer surface 460 of the pump bulb 408), a length L, and a width W. The lengths of the projections 472 and 474 are larger or greater than the widths of the projections 472 and 474. In the illustrated embodiment, the length L of each of the projections defines an axis D of the projections. Specifically, the length L extends along the axis D.

The pump bulb 408 has a first end portion 480 and a second end portion 482 disposed opposite the first end portion 480. The pump bulb 408 defines an axis DX that extends from the first end portion 480 to the second end portion 482. In the illustrated embodiment, the horizontal projections 472 include a curvature in the length direction. In other words, the horizontal projections 472 do not extend linearly in the length direction. The vertical projections 474 extend (along the length) in a direction substantially parallel to the axis DX of the pump bulb 408.

In the illustrated embodiment, the pump assembly includes eight horizontal projections 472 and four vertical projections 474. In other embodiments, the pump assembly includes a different number of horizontal projections (such as more than eight or less than eight). Similarly, in other embodiments, the pump assembly includes a different number of vertical projections (such as more than four or less than four).

As best illustrated in FIG. 6, two of the horizontal projections 472 and two of the vertical projections 474 form a receiving location 490. The receiving location 490 is configured to receive or partially receive a finger or a portion of a hand of a user to facilitate the actuation of the pump bulb 408. The horizontal projections 472 and the vertical projections 474 help prevent the pump bulb 408 from slipping from the grip of the user. For example, the horizontal projections 472 may help prevent the pump bulb 408 from slipping vertically and the vertical projections 474 may help prevent the pump bulb from slipping horizontally. The projections may also help prevent the pump bulb 408 from rotating during the pumping or actuation by the user.
